Industry segments are distinctive subsets of the larger industry along lines such as geography, product or service type, channel, customer or consumer needs, and so on. Mapping industry segments is rarely straightforward; it takes work, reflection, and, often, the willingness to explore beyond the current or obvious segments to segments that do not currently exist. In many cases, the accepted, traditional industry maps are imperfect. Like the old maps of a flat world that showed edges you could sail off, industry maps have limitations; only by exploring the edges of those maps can you see things differently.
